How to buy HDMI high-definition cable? HDMI cable purchase notes

 　　As one of the contemporary high-definition transmission cables, HDMI cables are used in many fields. This has also led to many brands of HDMI high-definition cables on the market. For consumers who have little contact, they are not clear about the matters that need to be paid attention to when buying HDMI high-definition cables. As a professional data cable manufacturer, Jianghan Electronics will tell you how to buy HDMI high-definition cables.

　　1, HDMI HD cable version

　　At this stage, the HDMI cable version 1.4 is the mainstream, which perfectly supports 4K resolution and 3D. Although many brands have introduced HDMI2.0 HDMI cables, consumers using version 1.4 HDMI cables are enough to meet the needs of home entertainment. It is worth noting that there are still some HDMI cables of version 1.3 or lower on the market. Consumers must be aware of it when purchasing.

　　2, HDMI HD line interface

　　The HDMI high-definition cable interface is a problem that consumers should pay attention to. Because HDMI high-definition cables have different interface sizes, how to buy the wrong interface size when buying, then it will not be used. Before buying, make sure that the display terminal is HDMI interface size, the width of micro HDMI is about 6 mm; the standard interface is HDMI (Type A), the width is about 15 mm; Mini HDMI, the width is 10.5 mm.

　　3, HDMI HD cable length

　　When buying an HDMI HD cable, you must first determine the length you need to avoid the situation where the length is not enough or the length is too long.

　　4, HDMI core needs all copper

　　Everyone knows that wire is the core bearer of data transmission. To reduce loss in signal transmission, it is necessary to choose all-copper cores. HDMI high-definition cables with all-copper cores have the ability to support ultra-long-distance transmission. Stable signal transmission.

　　5, HDMI high-definition cable can not be too thin

　　Signal loss will occur during the transmission process, and interference caused by external factors to the wire is also one of them. Many data cables have a shielding layer during production. The shielding layer of HDMI high-definition cables that are too thin are basically "shrinked" , So you can’t choose a too thin HDMI cable.

　　The above factors are the things to pay attention to when purchasing HDMI high-definition cables, especially the size of the HDMI cable interface and the HDMI cable version. If the purchased version is too low, it will not be supported. If the interface size is wrong, it will not work properly. Oh.

What is the reason for the hardening of the data line?

 　　In the current technological age, mobile phones have become one of the products that we cannot do without, and the data cable, as a product that we charge our mobile phones every day, will naturally be used every day. When you use the data cable, many people will encounter it. The data line becomes hard, especially the longer the time is used, the data line feels hard. What is the cause? Now Jianhan will tell you the reasons.

　　The problem of hardening of the data cable, if you have paid attention to it, you will find that the hardening of the data cable occurs almost in winter or when the weather is relatively cold. This situation is mostly caused by the heat caused by the cold weather. Expansion and contraction, as the weather becomes cold, the data line shrinks, and the data line feels hard.

　　

　　The standard analyzed from the professional point of view of the data cable manufacturer should be the aging of the plastic material caused by grease corrosion or oxidation, so it may become hard. The outer protective layer of the USB data cable in these products is mostly rubber products. The rubber products themselves will change due to temperature differences, but the state after this change is not lasting. Generally, as the temperature returns to normal, it will return to normal. .

　　For the thin layer of rubber on the USB data cable, if it is oxidized or corroded by grease, the USB data cable will become permanently hardened to varying degrees and cannot be restored. Good USB data cables are basically the same.

　　There are also some USB data cables that are not rubber appearance but the outer protective layer of woven data cables. The aging resistance of such data cables will be stronger than that of rubber.

　　The various USB data cables currently produced by Jianhan are mostly made of TPE or woven materials, which are not easy to break or deform, and are resistant to dirt and discoloration. If the weather is cold, the data cable feels hard. It’s normal, no need to worry about it. It’s the same as our body. Your fingers will become stiff in cold weather, and the data cable will be the same. When the weather is cold, it’s normal that the shell will harden.

What is the difference between HDMI high-definition cable and ordinary cable?

 　　What is the difference between HDMI high-definition cable and ordinary cable? Many people have gradually discovered that many electronic devices in our lives have gradually added an HDMI high-definition cable interface, such as our TVs, computers, etc., will have HDMI interfaces, many friends I don’t know what the HDMI interface is for. What is the difference between HDMI high-definition cable and ordinary cable? Today, Jianghan Electronics will tell you what the difference is.

　　Different resolution:

　　1, ordinary video cable: support 576P resolution;

　　2, HDMI high-definition cable: support 1080P high-definition video.

　　Support different channels

　　1. Ordinary video cable: does not support 8-channel 96kHz or mono 192kHz digital audio transmission;

　　2, HDMI high-definition cable: supports 8-channel 96kHz or mono 192kHz digital audio transmission.

　　Other differences:

　　1, the physical properties of the insulating layer are different;

　　2, the core wire diameter is different;

　　3. The above two fundamental differences determine the transmission characteristics of the two cables-the transmission attenuation is different;

　　4. The obvious characteristics of high braided cables are: low DC resistance of the shielding layer and reduced low-frequency attenuation below 200KHz, which is beneficial to suppress low-frequency interference. In terms of frequency distortion, high braided cables are more serious. The direct influence of frequency distortion is the normal proportional distortion of the various frequency components of the video signal, which directly affects the image distortion;

　　5. Copper-clad steel core wire: This is a type of SYWV cable, used for radio frequency transmission above 46MHz for CATV, and the 0-200KHz low frequency attenuation is too large.

　　The above is the difference between HDMI high-definition cable and ordinary cable. If you are buying HDMI high-definition cable, you must first check whether your device supports HDMI function, because some devices still do not support HDMI high-definition cable. If you are a distributor of HDMI high-definition cables, welcome to consult Jianghan Electronics. Jianghan Electronics has focused on the R&D and production of electronic cables for 13 years. HDMI HD cables are one of them. Factory direct sales, beautiful prices, consultation telephone: 0769-87815809

Precautions for choosing a wiring harness manufacturer

 　　In the current e-commerce era, various brands have sprung up like bamboo shoots after a rain, especially when mobile phones have become products that people cannot leave, all kinds of wires around their products have naturally become popular products. Many people rely on selling mobile phone peripheral wire harnesses. Good results have been obtained, and this has also led many people to want to join the game. In today’s era, when entering e-commerce, products are the top priority. How to choose a wire harness processing manufacturer has become the key point. Today Jianghan Electronics will give you all Share the precautions for choosing a wiring harness manufacturer, let's take a look.

　　1, Product quality considerations

　　The product is the core, and the quality of its products is naturally the center of gravity, and it is also the first thing we need to pay attention to. Generally, manufacturers will have samples. In terms of products, it is best to test and use by yourself to check the quality of the products. This is also for future business. Have a direct impact.

　　2, product richness

　　In the current e-commerce era, the competition is fierce, and the richness of products has become a new selling point. After all, people nowadays like personalization. If your product is too single, it is difficult to meet the needs of users. If the product is rich, The opportunities for competition will also be greater. And the manufacturers with abundant products reflect that the manufacturers are advancing with the times, conform to the trend of the times, and are not complacent.

　　3, manufacturer equipment considerations

　　The equipment of the manufacturer is also a consideration. The equipment mainly affects two points. The first is the efficiency of production, and the second is the pass rate of the product. The issue of production efficiency is relatively not a big problem, after all, the wire rod The production mechanization is relatively complete, and the production efficiency is relatively not too low. The main problem is the pass rate of the product. If the machine is too old and prone to problems, the quality of the product may be somewhat unstable.

　　4, Wholesale prices

　　In the final analysis, price is a top priority. In terms of price, there is nothing to say. It is best to shop around and focus on comparison in terms of quality and price.

　　5, Factory service

　　The manufacturer’s services are relatively rich. We are new. If we do everything ourselves, first, we don’t know where to start, and second, it will increase a lot of trouble, such as the packaging of wires or other things. It will take a lot of effort if you do it yourself. If the manufacturer can provide these services, it will be much more convenient. In addition, the attitude of the sales staff. If the attitude of the sales staff is not good, it will be a trouble for some follow-up service problems. Therefore, this It is also a key consideration.

What is the difference between a USB data cable and a charging cable?

 　　What is the difference between a USB data cable and a charging cable? The two vocabularies of USB data cable and charging cable are one of the most common vocabularies in our daily life. These two vocabularies are very related to our mobile phones, but many people are concerned about these two words. The difference between the two is not clear. As a professional data cable manufacturer, Jianghan Electronics will tell you the difference between the USB data cable and the charging cable today. Let’s take a look.

USB data cable

　　distinguished from function:

　　If the USB data cable and the charging cable are distinguished by function, the difference is still quite big. The USB data cable can be seen from the literal meaning that it can carry out data transmission, and the charging cable is for charging.

　　distinguished from appearance:

　　The USB data cable and the charging cable also have a big difference in appearance, that is, the thickness of the two cables. The data cable is relatively thicker. There are four cables inside, while the charging cable is relatively thin because there is only Two lines.

　　The four wires in the USB data cable already include two of the charging cables, so this is why the data cable can both transmit data and charge, while the charging cable only has the function of charging and cannot transfer data. In the past , Some data cable manufacturers will regard these two products as two products when they are in production, but with the rapid development of the times, the current cables are basically made of data cables, and there are few simple charging cables. .

　　After reading the above introduction of Jianghan Electronics, you must have a clear understanding of the difference between USB data cables and charging cables. For more professional knowledge about data cables and wires, please continue to pay attention to Jianghan Electronics, Jianghan Electronics As a participant in the formulation of Guangdong regional data line standards, he has rich experience in data line R&D and production, supports ODM&OEM services, and welcomes distributors for wholesale purchases

What are the types of mobile phone data lines

　　The mobile phone data cable is a cable used to connect the mobile phone to the computer, and has the functions of charging and data transmission. The model of the mobile phone data cable was like this at first.

　　In that era, every time you change a mobile phone, you have to change a data cable, which is very inconvenient.

　　There are three types of mobile phone data cables currently on the market, namely: Micro-USB, Type-C USB, and Lightning. Let me talk about the characteristics of these three data lines.

　　1, Apple Lightning data cable

　　First of all, the number one in the mobile phone industry, Apple has always been known for its closed system. Of course, there is no exception in the data interface. The Lightning interface is exclusively for Apple mobile phones. He has the following characteristics:

　　Small size, there are 8 contacts on both sides of the Lightning interface, and the function of each contact is defined by the digital chip, which greatly reduces the space at the bottom. Apple officially announced that it can reduce the volume by 80%.

　　The front and back are common, regardless of the front and the back. It is also very important for the user. The previous 30-pin interface is very difficult to distinguish the front and the back. When inserted, if the direction is wrong, it will easily cause physical damage to the entire card slot.

　　Easy to clean, there will be a small groove next to the contacts of the Lightning interface, with a relatively low arc. At the same time, the application of new materials makes the interface easy to keep clean.

　　2, Android Micro-USB interface data cable

　　Micro-USB is a portable version of the USB2.0 standard, which is smaller than the MiniUSB interface used by some mobile phones. Micro-USB is the next-generation specification of Mini-USB. The formulation was completed on the 4th. He has the following advantages:

　　supports hot-swappable, it can be directly plugged and unplugged when in use, and does not need to be shut down to operate, which is convenient for users.

　　Unified standard specification, Micro-USB is the first unified mobile phone data interface. From then on, you don't need to lose the data cable when you change your mobile phone.

　　10,000 times the service life.

　　3, Type-C data cable

　　Type-C USB can be said to have many advantages, the following is a list for everyone:

　　Fast, theoretically, the highest transfer rate of Type-C USB port is 10Gb per second.

　　All-rounder, the Type-C USB port of the new MacBook can transfer data, charge it, and can also be used as a video output port to connect to external display devices. The only question is how Apple satisfies users who want to do these three things at the same time.

　　Two-way, unlike the old USB interface, which can only transmit in one direction, the transmission of the Type-C USB interface is two-way, which means that it can have two sending methods at the same time.

　　is backward compatible, Type-C USB can be compatible with the old USB standard interface, but an additional adapter is required to complete the compatibility.

　　Ultra-thin, thinner port, which is one of the reasons why Type-C USB was born. The Type-C USB port is 0.83 cm long and 0.26 cm wide, while the old-fashioned USB port is 1.4 cm long and 0.65 cm wide.

　　There is no front and back. Like Apple's lightning interface, the front and back of the Type-C USB port are the same. That is to say, no matter how you insert it, it is correct. Don't worry about the pros and cons of traditional USB ports.

　　I believe that Micro-USB data cables will gradually disappear in the future, and Type-C USB will be used more and more.

What kinds of USB data cables are there?

　　The USB data cable is one of the daily necessities that we cannot do without. Everyday charging of mobile phones, or data transmission between computers and mobile phones, etc., will often use data cables, but there are also different types of data cables. Today, Jianghan Electronics will tell you what kinds of USB data cables are available. Let’s take a look.

　　What kinds of USB data cables are there?

　　1, ordinary USB data cable

　　The reason why the ordinary USB data cable is ordinary is because it has no central controller and must be plugged into the mobile computer to recognize the cable. This kind of cable is simple in structure and cheap.

　　2, with IC USB data cable

　　IC is the central control chip. This kind of cable has its own central control chip, so it can recognize the line without plugging in a mobile phone or computer. However, the price of IC is relatively expensive, usually more than 10 yuan, so the price of data lines has also increased a lot. .

　　3, special USB data cable

　　The special USB data cable mentioned by Jiang Han here is also with IC, but the IC chip is more special, usually dedicated chip, the model is usually: DKU-5, CA-42, DCU-11 and so on.

　　Jiang Han would like to remind everyone here that everyone should not have false perceptions, and don’t blindly think that the quality of the data cable with IC is good, and the quality of the data cable without IC is poor. This is wrong. The USB data cable is of poor quality. The quality is not determined by the IC. With or without the IC chip is determined according to the applicable model of the mobile phone, and the quality is determined according to the production of the data cable manufacturer.

What is the Type-C data cable?

　　type-c data cable refers to the data cable of the USB Type-C interface. USB Type-C is abbreviated as Type-C, which is the hardware interface specification of Universal Serial Bus (USB). The biggest feature of the Type-C interface is that it supports double-sided insertion of the USB interface, which formally solves the worldwide problem of "USB is never inserted correctly". At the same time, the USB data cable used with it must be thinner and lighter.

　　type-c data cable refers to the data cable of the USB Type-C interface. USB Type-C is abbreviated as Type-C, which is the hardware interface specification of Universal Serial Bus (USB).

　　The highlight of the Type-C interface is a slimmer design, faster transmission speed (USB3.1 up to 10Gbps) and stronger power transmission (up to 100W).

　　The biggest feature of the Type-C double-sided pluggable interface is to support double-sided insertion of the USB interface, which formally solves the worldwide problem of "USB is never inserted correctly". At the same time, the USB data cable used with it must be thinner and lighter.

　　The advantages of Type-C interface data cable:

　　1. The interface is extensible

　　Type-C interface has strong scalability, can transmit video and audio signals, can be extended to HDMI, VGA, DVI and other audio and video output interfaces, and can even be extended to 4K resolution.

　　2. Two-way charging is possible

　　Type-c interface can provide two-way power supply, which can charge the device itself or supply power to external devices.

　　3. Stronger data transmission capacity and higher charging power

　　USB Type-C was mass-produced in August 2014, adopting the 3.1 standard. Compared with the USB2.0 interface used in early smart phones, the transmission speed is much higher, and the maximum data transmission speed can reach 10Gbit/sec. The type-c supports the USB-PD power supply standard, and the maximum power supply can reach 100 watts.

　　4. The interface is lighter and thinner

　　Different from the traditional USB Type-A and Type-B interfaces commonly used in life, the new Type-C interface is slim in size, only 8.3*2.5mm, which is more suitable for use in increasingly miniaturized electronic products and devices.

　　5. Support front and back insertion

　　In the past, Android phones were basically Micro USB ports, while Micro USB ports were trapezoidal ports. The data cable can only be plugged in the front, and sometimes it cannot be plugged in after repeated attempts to charge at night. The Type-c interface perfectly circumvents this shortcoming. The shape of the type-c interface is an oval interface, which supports positive and negative insertion, which is more convenient to use.
